Accidentally deleted Google account, recovered it but now having loads of problems

[Zig666]

I was using a Samsung device for work &they wanted me to return it but asked me not to factory reset it,  to just remove my Google account,  I accidentally deleted my Google account from all my devices. 

Managed to recover it but now my Google home app won't let me reconnect my nest doorbell battery, nest hub max (camera) & nest cam outdoor battery. 

When I try ,it fails when trying to retrieve the password automatically saying "trouble connecting to Google  account ".

Have already factory reset doorbell. 

All other smart  devices show up in home app ,although I never connected them after account recovery, but if I  try and create a group it says I don't have permission to do that on account #.
